@BISCUITS i moved the light up to about 15" away from the tops. They're getting about 50K lumens at the top. They seem to be doing fine still, but yeah, I think your assessment was spot on. I had hit them a little heavily with water and light for the few days preceding. I'm giving them a few days in between watering now instead of every 1-2 days. Still getting the hang of watering these smaller 1 and 2 gallon pots. I usually use 3 or 5 gallon ones.
I picked up a Control Wizard Accurate PH8 soil meter and used it for the first time today. It's huge! I've had a couple soil pH meters before and they all seemed to be pure shit. This one seems to be giving me accurate readings. My soil is reading at about 6.6 - 6.7, which seems perfect to me.
I watered them a couple days ago with a gallon of water and a teaspoon of Neptune's Organic Fish Hydrolysate(2-4-1) and a little under a ml of Mammoth P. I was a little concerned about using the liquid fish as its high in P and has phosphoric acid in it. The Rev wasn't entirety clear on this. On the one hand, he praises liquid fish fertilizer in his book, but then cautions against watering with any liquid fertilizers, particularly with high levels of P. He says it can throw off the balance of fungus and bacteria in the soil. I read through all his articles in Skunk magazine and it seems like he's done a complete 360 on much of the advice and principles he outlined in his first edition of TLO. So, I'm taking his advice with a grain of salt. My soil pH seems fine a couple days after I used it, so I think it's OK.
My Sour Crack are at about 52 days old now, so it looks like I've got a couple weeks or so left until harvest! I ordered some Serenade fungicide to head off any potential botrytis issues, which I get sometimes with dense buds like Sour Crack. I've also got two clip-on fans running in my tent and the exhaust at full blast to keep the air circulation good.
The White Crack and gimpy AvT are looking good too. I'm kind of glad I let the AvT keep going as she's putting out some nice healthy looking new growth. I don't think the other AvT I planted is going to pop. I'll wait until I get my Rapid Rooters in the mail and try using one of those. I may also stick my germination pad under the pot to keep it a little warmer. Temps in my tent are about 66-67F in the shade and 75F at the Tops according to my infrared thermometer.
I'll get some pics up in the next few days.
